Description

Straight and curved screen cutting machine

technical field

The invention protects a cutting machine, in particular a straight-faced and curved screen cutting machine, and belongs to the technical field of mobile phone repair equipment.

With the development of electronic products such as mobile phones and tablet computers, their applications in people's lives are becoming more and more extensive. At present, the screen ratio of mobile phones, tablet computers, etc. is getting larger and larger, and even products such as full screens appear. During the use of such electronic products, it is easy to cause screen protection glass due to extrusion, accidental dropping or other reasons. If it is damaged, it needs to be replaced or repaired. The cover plate and the middle frame of the mobile phone screen are fixed with glue. During after-sales maintenance, in order to disassemble the screen and the cover plate, the screen protection glass is often heated and used for disassembly. The disassembly method of the tool pry is easy to damage the LCD screen. In order to solve this problem, a screen cutting machine is invented. When removing the screen protective glass, the screen protective glass is cut by the screen cutting machine to facilitate its removal.

The flat working platform of the prior art screen cutting machine is fixed on the bottom plate, and the inclined working platform can be rotated to adjust its inclination angle. When it is placed horizontally, it can be used to cut a straight screen (or a flat screen). Can be used to cut curved screens when tilted. The purpose of the inclined working platform can be rotated to adjust the angle. When cutting the straight screen, it can be adjusted into a plane, which is connected with the plane working platform to become an integrated platform.
